[0037] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0039] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium, internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on specific circumstances.

[0040] refer to Figure 1-3 , an embodiment of the present utility model shows an anti-glare cover, comprising a face mask 1, a prismatic plate 2 and a diffuser plate 3;

[0041] The mask 1 includes a main body 11, on which at least two oppositely arranged mounting strips 12 are provided, a snap-fit ​​portion 121 is provided on the outer side of the mounting strip 12, and a rib 122 is provided on the inner side of the mounting strip 12, and a clamping space 123 is formed between the rib 122 and the main body 11; the prism plate 2 and the diffuser plate 3 are stacked on the main body 11, and the edges of the prism plate 2 and the diffuser plate 3 are clamped in the clamping space 123.

[0042] In the above solution, the face shield 1 is made of PC (Polycarbonate), a common material for lamp face shields 1. The face shield 1 is light-transmissive and shields the light source module 300 within the lamp, protecting it from external contamination and physical damage, such as dust, oil, and accidental collisions. In this embodiment, the face shield 1 also secures the prismatic plate 2 and diffuser plate 3 via a clamping space 123 formed on the mounting bar 12, integrating the face shield 1, prismatic plate 2, and diffuser plate 3 into a single component for easy installation on the lamp.

[0043] Among them, such as Figure 2 and Figure 6 As shown, the diffuser plate 3, the prism plate 2 and the main body 11 are stacked in sequence; when light passes through the anti-glare cover 100, the diffuser plate and the prism plate 2 diffuse the light and control the beam angle, thereby reducing glare.

[0044] Preferably, the height of the clamping space 123 can be set to be equal to or slightly less than the sum of the thicknesses of the prism plate 2 and the diffuser plate 3, so that the prism plate 2 and the diffuser plate 3 will not shake when they are set on the mask 1, and even the ribs 122 can be used to apply extrusion pressure to the prism plate 2 and the diffuser plate 3 to clamp the prism plate 2 and the diffuser plate 3 on the main body 11, thereby improving the installation stability of the prism plate 2 and the diffuser plate 3; it should be noted that the mask 1 is made of plastic materials such as PC and has a certain ductility, so the ribs 122 and the main body 11 will not cause physical damage to the prism plate 2 and the diffuser plate 3.

[0045] The above scheme is specific, such as Figure 3 As shown, the cross-section of the mounting bar 12 includes, from near to far, a rising section 12a, a first inclined section 12b, and a second inclined section 12c, based on the main body 11. The first end of the first inclined section 12b is connected to the rising section 12a, and the second end of the first inclined section 12b is connected to the first end of the second inclined section 12c. The first inclined section 12b is inclined away from the rib 122 from its first end to its second end, and the second inclined section 12c is inclined toward the rib 122 from its first end to its second end. The latch portion 121 is formed between the first inclined section 12b and the main body 11. The latch portion 121 is a slot structure. The rising section 12a is used to create a certain space between the first inclined section 12b and the main body 11, thereby forming the latch portion 121. The rib 122 is provided at the connection between the rising section 12a and the first inclined section 12b.

[0046] In order to explain the working principle of the specific structure of the above-mentioned mounting strip 12, a lamp is provided, such as Figure 4-6 As shown, the lamp includes the above-mentioned anti-glare cover 100 and a lamp box 200, and the lamp box 200 is provided with a lamp cavity 210 having a light outlet (not marked in the figure), and the lamp cavity 210 is provided with a light source module 300. The inner wall of the lamp cavity 210 is provided with a clamping strip 220, and the clamping strip 220 forms a clamping connection with the buckle portion 121 of the mask 1, so that the mask 1 covers the light outlet of the lamp cavity 210.

[0047] Among them, such as Figure 6As shown, when the anti-glare cover 100 is installed on the lamp box 200, the second inclined section 12c on the mounting strip 12 will be squeezed by the clamping strip 220, so that the mounting strip 12 is tilted in the direction of the rib 122. When the clamping strip 220 passes over the second inclined section 12c, the mounting strip 12 is reset, and the clamping strip 220 is clamped between the first inclined section 12b and the main body 11, that is, clamped in the buckle portion 121, thereby completing the installation of the anti-glare cover 100; when disassembling, the anti-glare cover 100 is pulled out in the direction away from the lamp box 200, and the first inclined section 12b is squeezed by the clamping strip 220, so that the mounting strip 12 is tilted in the direction of the rib 122 until the clamping strip 220 passes over the first inclined section 12b, thereby achieving separation between the mounting strip 12 and the clamping strip 220.

[0048] In the above solution, during the installation and removal process, the installation bar 12 will tilt in the direction of the rib 122. Therefore, in order to prevent the prismatic plate 2 and the diffuser plate 3 from hindering the tilting deformation of the installation bar 12, in this embodiment, Figure 6 As shown, there is a gap 4 between the prismatic plate 2, the diffuser plate 3 and the mounting bar 12; specifically, the width of the gap 4 can be set to 0.5-2 mm.

[0049] Specifically, if Figure 5 As shown, the lamp is a linear lamp, the lamp box 200 is an elongated profile, the mask 1 is correspondingly elongated, and two mounting strips 12 are provided on the main body 11. In other embodiments (not shown), the lamp box 200 can be of other shapes, such as a square, the mask 1 is correspondingly square, and four mounting strips 12 can be provided on the main body 11, with the four mounting strips 12 arranged in a quadrilateral.

[0050] In the above scheme, if Figure 4 and Figure 5 As shown, specifically, the lamp box 200 is made of aluminum to improve the heat dissipation efficiency of the light source module 300; a driving power supply 400 is provided on the lamp box 200 and the driving power supply 400 is covered and protected by a cover plate 500; end covers 600 are provided at both ends of the lamp box 200 to seal the end covers 600 of the lamp box 200 to prevent dust from easily entering the interior of the lamp box 200.

[0051] In summary, the present application provides an anti-glare cover and a lamp containing the same, in which the edges of the prism plate 2 and the diffuser plate 3 in the anti-glare cover 100 are clamped in the clamping space 123 of the main body 11 of the mask 1, realizing the function of quick installation and disassembly without tools, greatly shortening the time required for installation and disassembly, and improving work efficiency; this design also facilitates the upgrading of lighting products, and the prism plates 2 and diffuser plates 3 of different specifications or designs can be easily replaced as needed to meet personalized lighting needs; the clamping space 123 provides a firm and gentle support for the prism plate 2 and the diffuser plate 3, avoiding physical damage such as scratches and deformation that may be caused by traditional fixing methods (such as screw fixing or pressing), thereby ensuring the integrity and performance of the optical components and ensuring good lighting effects and anti-glare performance.

[0052] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
